The first step to using your camera and blobfinder is to identify which drivers support your devices, and create a configuration file. To find a driver that supports your camera, see the list of [http://playerstage.sourceforge.net/doc/Player-svn/player/group__drivers.html Available Drivers]. Once you find a driver that supports your camera and/or blobfinder, you will need to create a configuration file. For more information on writing configuration files, see [[Writing configuration files]].

Player comes with a client program called "playercam" that subscribes to camera interfaces and displays the available image and blobfinder data. To use it, start Player in a terminal window with your configuration file:

<pre>

<pre>

+

$ player cameraconfig.cfg

+

</pre>

+

+

And in a second terminal window, run the playercam utility.

+

<pre>

+

$ playercam

+

</pre>

+

+

Playercam accepts a number of different command line options to control which Player server and interfaces to connect to. Type "playercam -help" to see the usage.

Creating a Configuration File

The first step to using your camera and blobfinder is to identify which drivers support your devices, and create a configuration file. To find a driver that supports your camera, see the list of Available Drivers. Once you find a driver that supports your camera and/or blobfinder, you will need to create a configuration file. For more information on writing configuration files, see Writing configuration files.

Testing your camera

Player comes with a client program called "playercam" that subscribes to camera interfaces and displays the available image and blobfinder data. To use it, start Player in a terminal window with your configuration file:

$ player cameraconfig.cfg

And in a second terminal window, run the playercam utility.

$ playercam

Playercam accepts a number of different command line options to control which Player server and interfaces to connect to. Type "playercam -help" to see the usage.

playercam - camera test utility for a player camera
USAGE: playercam [options]
Where [options] can be:
-help : print this message.
-h <hostname> : host that is running player
-p <port> : the port number of the host
-i <index> : the index of the camera
-b <index> : the index of the blobfinder
-r <rate> : the refresh rate of the video
-t <transport> : transport to use (either "tcp" or "udp")
Currently supports RGB888 and 8/16-bit grey scale images.

PlayerC++ client program

The following program is available in the Player source tree, at examples/libplayerc++/camera.cc. This program subscribes to a camera interface from a Player server using the PlayerC++ CameraProxy, and uses the CameraProxy to save images from the server to disk. For all available methods in the CameraProxy, see the CameraProxy documentation.
